24 hours Marathon

   On 16 September 2026, from 14:00 to 16:00 (online), we will host a free webinar dedicated to a topic that is of growing interest worldwide: the validation of odour dispersion models using the grid method defined in EN 16841‑1.

   Consultants run odour dispersion models around the world, but because odour concentration is difficult to measure reliably in ambient air, there is no practical way to know whether the model predictions are right or wrong. With the approach developed and applied in Germany, Austria and Switzerland, along the last over 40 years, it is possible to check the performance of a model and verify whether an odour dispersion assessment has been done correctly against field measurements.

Be part of the 24h-MOM audience

    The 24-hour Marathon on Odour/Odor Management (24h-MOM) will bring together experts in the field of odor from all over the world for an intensive day of presentations and round tables in which more than 10 topics will be addressed.

   This conference is free of charge and supported only by some fantastic sponsors who make it possible to hold a global event like this. So thank you! This event is also non-profit. Meaning that any extra funds raised will go to the participating organiz/sations. One of the ideas on the table is to cover the cost of student attendance at one of the conferences on odour/odor management organiz/sed by these organiz/sations. Another idea is to support initiatives or meetings, for example by paying for coffee breaks at partner meetings. Olores.org (a brand of the private company Ambiente et Odora), which is coordinating the work, will not receive any remuneration of any kind. Neither will any of the members of the coordination committee. The only goal and benefit here is to have FUN.

   Don't hesitate to attend this event on the 12th of November for FREE!
